Which of the following is NOT a symptom typically associated with autism?

Excessive social interaction is not a symptom typically associated with autism. Rather, individuals with autism spectrum disorder often exhibit difficulties in social communication and interaction. They may struggle to engage in reciprocal conversations, understand social cues, or develop friendships in typical ways. This contrast is foundational to the diagnosis of autism, which is characterized by challenges in social engagement and often includes behaviors such as poor eye contact, delayed language development, and the pursuit of specific, intense interests. These traits underscore the social and communicative difficulties faced by individuals on the spectrum, making excessive social interaction an atypical characteristic.
